Maintenance
At GEPL, we ensure the reliability and performance of your electrical systems through specialized maintenance of transformers, switchgear, breakers, protective relays, and other critical components. Our experienced engineers and technicians manage high-voltage networks, including switchgear, transformers, and substations up to 33kV. We offer tailored maintenance strategies, from short-term fixes to long-term contracts, to keep your operations running smoothly. In the event of unexpected electrical failures, our 24/7 emergency service guarantees that we’ll be there when you need us most.
Preventative Maintenance
We design maintenance schedules and checklists for electrical equipment, switchgear, and panels, guided by OEM manuals and Indian standards. Our services include thorough checks on key components such as:
​
-
Ring Main Units (RMU) up to 22 KV
-
High Voltage Circuit Breakers : Vacuum and SF6 Circuit Breakers up to 33 KV
-
Protection Relays (HV and LV sides)
-
Transformers : Oil-filled and Dry Type
-
Low Voltage Panels : Air and Moulded Case Circuit Breakers
-
Capacitor Banks
-
Power Distribution Boards
​
Our approach ensures that your electrical systems remain reliable and efficient, meeting the highest industry standards.​​​​​​​​​​

This comprehensive approach ensures reliable and safe operation.
Thermographic Imaging
GEPL offers Infrared Thermographic Imaging services as part of proactive maintenance for electrical panels and equipment, which also forms a key component of our Electrical Safety Audit (ESA). Using advanced FLIR Thermography Cameras, we adhere to stringent standards that accurately assess the heating effects of electrical currents, eliminating any misleading analysis of hotspots.
Thermographic Imaging benefits our clients by:
-
Preventing short circuits or fires caused by incipient faults or loose terminations.
-
Identifying loss-producing conditions to minimize unplanned outages.
-
Allowing controlled repair scheduling around production timelines.
-
Reducing downtime, preventing unwanted business interruptions.
-
Extending the useful life of electrical switchgear and equipment.

​
-
Meggering to identify the faulty cable
-
Phasing
-
Pinpointing the fault location
-
Safely cutting the identified cable
-
Arranging jointing materials and cable
-
Meggering of the healthy cable portion
-

Cable Jointing & Terminations
Cable jointing and terminations are critical steps following cable fault finding. When a cable fails, removing the damaged section and replacing it with a new length through jointing is the most effective solution. GEPL specializes in High Voltage Cable Jointing services for LV to HV cables up to 33 kV. We provide various jointing types, including Straight Through Joints and Transition Joints.
Proper termination is essential for connecting cables to equipment like circuit breakers, transformers, and motors. GEPL ensures flawless terminations by using reliable termination kits with proven test results. Our teams are trained in the latest technologies, including cold shrink and heat shrink products from top manufacturers like Raychem and 3M.
Our experienced jointers complete these tasks efficiently for our valued industrial and commercial clients.
​
We offer various termination kits, including:
-
Indoor termination kits
-
Outdoor termination kits
-
End sealing kits
